The demographics of the Canadian swine industry is such that there is concentration in the hog production with regard to size; this is most evident in Quebec where the data are most fragmented, but this appears to be broadly the case- a small number of large farms produce the bulk of market hogs and hold the bulk of the sows. Secondly, the hog production segment has declined across the country. This is particularly the case in western Canada and Ontario, but also in Quebec. Finally, the pork packing segment is relatively concentrated, with the hog production segment increasingly sized to the packing segment. The potential implication of this is to allow, prospectively, packing system alignment back to the farm level.
